What does adding lye to goats milk do?

Answer 1

Adding lye to goat's milk is a critical step in the process of making traditional soap, specifically in the saponification process. Lye, or sodium hydroxide, reacts with the fats and oils in the milk, producing glycerin and soap. This process not only helps in creating a solid bar of soap but also contributes to the soap's moisturizing properties, as goat's milk is rich in vitamins and fats. However, it's important to handle lye with caution, as it is a caustic substance.
